An implementation of a code generator for BPF programs to speed up packet
filtering on PPC64, inspired by Eric Dumazet's x86-64 version.Filter code is generated as an ABI-compliant function in module_alloc()'d mem
with stackframe & prologue/epilogue generated if required (simple filters don't
need anything more than an li/blr). The filter's local variables, M[], live in
registers. Supports all BPF opcodes, although "complicated" loads from negative
packet offsets (e.g. SKF_LL_OFF) are not yet supported.There are a couple of further optimisations left for future work; many-pass
assembly with branch-reach reduction and a register allocator to push M[]
variables into volatile registers would improve the code quality further.This currently supports big-endian 64-bit PowerPC only (but is fairly simple
to port to PPC32 or LE!).Enabled in the same way as x86-64:
echo 1 > /proc/sys/net/core/bpf_jit_enable
Or, enabled with extra debug output:
echo 2 > /proc/sys/net/core/bpf_jit_enable

Newer VPD datablocks can exceed the size the tg3 driver is traditionally
used to. This can cause some of the routines that operate on the VPD
data to fail when in-fact they could have succeeded had they known the
correct size. This patch fixes the problem.Signed-off-by: Matt Carlson

Occasionally, when the network cable is removed after a successful
autonegotiation, the device will not send a link down interrupt to the
driver. This happens because of a bad interaction of an EEE
workaround. The fix is to adjust the code so that the root cause
condition does not happen.Signed-off-by: Matt Carlson

Commit f2096f94b514d88593355995d5dd276961e88af1, entitled
"tg3: Add 5720 H2BMC support", needed to add code to preserve some bits
set by firmware. Unfortunately the new code causes throughput to stop
after a chip reset because it enables state machines before they are
ready. This patch undoes the problematic code. The bits will be
restored later in the init sequence.Signed-off-by: Matt Carlson

This patch fixes both the failure in the self-test on 578xx
and a hole in a parity recovery flow that this failure
has discovered:
- internal 'pending' state in a VLAN_MAC object wasn't been cleared
when the object state change was called with DRV_ONLY flag, which in
particular happens when a parity error happens during the self-test.
- bp->sp_state wasn't cleared in the similar circumstances as described
above.Signed-off-by: Vladislav Zolotarov

Fix the parity errors recovery flow for 578xx:
- Add a separate column for the 578xx in the parity mask

- Fix the bnx2x_process_kill_chip_reset() to handle the blocks
newly introduced in the 578xx.Cover ATC and PGLUE_B blocks for 57712 and 578xx.
